小红叉显示如下：

Failure to transfer com.thoughtworks.xstream:xstream:pom:1.3.1 from https://repo.maven.apache.org/maven2 was cached in the local  repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could  not transfer artifact com.thoughtworks.xstream:xstream:pom:1.3.1 from/to central (https://repo.maven.apache.org/maven2): connect  timed out

金山词霸翻译后，大意如下：
在缓存本地仓库中没有找到插件com.thoughtworks.xstream:xstream:jar:1.3.1，在没有解决这个问题之前，是不会去从Nexus代理的中央仓库上去执行更新下载。

如何解决：
1、根据提示：com.thoughtworks.xstream:xstream:jar:1.3.1，找到本地仓库的相应jar包目录，删除
（maven的默认本地仓库在用户的.m2文件下，此目录为下图）

2、配置pom.xml依赖xstream，重新下载即可

<dependencies>     <dependency>          <groupId>com.thoughtworks.xstream</groupId>             <artifactId>xstream</artifactId>           <version>1.3.1</version>      </dependency></dependencies>
